Cody Wilson makes gun-making machines. Depending whom you ask, he's either one of the most dangerous people in the world, or a hero of the first amendment.

Cody's never sold a gun. He's never killed anyone. And, to his knowledge, none of the guns he's made have ever killed anyone. So, how did Cody Wilson end up on the frontline of the debate over gun control? He ended up there, not by selling guns, but by creating ways for anyone to make their own gun.

In 2013, Jackson Palmer started paying close attention to cryptocurrencies — bitcoin, and everything that came after. Things seemed a little bubbly.

Also big back in 2013: Doge, an Internet meme that featured an adorable dog and strange syntax.

Jackson sent off a random tweet about "Dogecoin" — just a throwaway joke. But one thing led to another, and Dogecoin became a real thing. Jackson tried to keep Dogecoin light and fun — it was for learning about cryptocurrency, and giving money to charity.

Last September, Energy Secretary Rick Perry put a plan in front of the Federal Energy Regulatory Commission. The plan was supposed to make our energy supply "resilient." But it was also a way to help subsidize coal.

The commission has five members. Four of them, including the chairman, were appointed by President Trump. This week, the commission unanimously rejected the Perry plan.

On today's indicator, we look at what the commission's decision tells us about energy markets in America, and about the future of coal.

The job market is strong right now, with a 4.1 percent unemployment rate, and President Trump knows it.

In his State of the Union address, he said he is "proud" that "African-American unemployment stands at the lowest rate ever recorded. And Hispanic-American unemployment has also reached the lowest levels in history."

Earier this month, he also bragged about the latest jobs report, focusing in on minorities in particular.

Income inequality is rising. Over the past few decades, the rich have seen huge gains, while incomes for the middle class and the poor have largely stagnated.

Lots of people have ideas for how to get middle-class incomes growing again. On today's show: Branko Milanovic, one of the most insightful economists we know on this subject, says a lot of those ideas won't be that helpful in the 21st-century economy. He has some surprising ideas about what will.

Plenty of people will tell you they're getting rich off of bitcoin. They could be right. But there's another group of bitcoin owners that aren't so ecstatic. Because they might be rich, too, but they lost the passkey that would let them get at their digital fortune. Syl Turner is in that second, less glamorous group. When he got around one-and-a-half bitcoins seven or eight years ago, they were nearly worthless. So worthless he bunked the hard drive that held the key somewhere and now he can't remember where.
